CROSS REFERENCE TO RELATED APPLICATION

Priority is claimed to U.S. Provisional Application No. 61/976,112 (filed on Apr. 7, 2014), which is incorporated herein by reference in its entirety.

FIELD OF THE INVENTION

The present invention relates generally to a sole for a shoe and more specifically, a dynamic sole for a shoe adapted to facilitate comfort and support for walking.

BACKGROUND

Today, most shoes include an insole and an outsole. Sometimes a midsole is provided as a layer between the insole and outsole. A shoe defines an interior cavity formed in an opening for receiving a human foot. Typically, the insole is provided along a floor of the interior cavity, which is in contact with the bottom of the foot during use. The outsole defines an outer portion of the shoe exposed to the surrounding environment. In use, the user wearing a shoe inserts his or her foot into the shoe through the opening, allowing the shoe to substantially form around the foot. The foot generally contacts the insole. The midsole, if one is provided, is sandwiched between the insole and the outsole, which is exposed to the external environment. Some shoes include a removable insole.

Currently, insoles are typically fabricated in a relatively low cost manner providing minimal support and/or minimal additional comfort. Consumers can purchase off the shelf inserts or supports to provide different or added comfort or support for their feet. For example, a consumer may replace the “factory” insole, which is included at the time of purchase of the shoe, with a more supportive arch support, cooling insole fabricated from a more breathable material, or an insole that includes additional padding.

Accordingly, a need exists for a shoe component operable for user customization to provide added comfort, support, and manufacturability in a competitive manner.

SUMMARY

The present disclosure generally relates to a shoe component (insole, midsole, and/or outsole) including: (a) a toe section, a heel section, a midfoot section positioned therebetween, an exterior side and an opposed interior side, both extending from the heel section through the midfoot section and to the toe section; (b) a closed cell foam heel cup positioned in the heel section; (c) a heel pad including any of foam, air, and a combination thereof, the heel pad positioned in the heel section at least partially surrounded by the heel cup; (d) a plurality of open cell foam members of varying firmness positioned in a movement pattern corresponding to a user's pressure movement pattern and extending through the midfoot section and into the toe section; and (e) an optional toe closed cell foam member as a filler positioned in the toe section. The movement pattern can correspond to a determined pressure pattern associated with a given athletic activity and the movement pattern defines a center path. The plurality of open cell foam members can be positioned on either side of the center path corresponding to a movement configuration of a user to provide varying support on either side of the center path.

The present disclosure relates to a shoe component (insole, midsole, and/or outsole). The shoe component can be incorporated into any conceivable footwear. Examples of footwear include but are not limited to: athletic shoes such as basketball, running, tennis, hiking, walking, cross training, biking, baseball, football, golf, etc., sandals, formal shoes, casual shoes, and the like.

Referring to FIGS. 1-3, example schematic sole layouts are provided. These layouts can be incorporated into an insole, a midsole, and/or an outsole. The configuration of each shoe component can correspond to a given pressure map or pattern generated by a given user or predetermined by a particular athletic activity. For example, when walking, a user typically places the foot onto a walking surface moving from heel to toe. This means that typically the heel strikes the surface first and then rolls through the midfoot to the toe. Based on a foot's shape and predetermined pressure pattern, a pressure path of the foot can be determined as the foot touches the walking surface with the heel until the foot pushes off with the toe.

Depending on the particular type of athletic or other activity, this pressure path or pattern can vary. The path can resemble a wave and define a center path, interchangeably referred to as a centerline. In the drawings, centerline 20 of FIG. 2 is shown for a right foot neutral configuration. In this example, centerline 20 begins slightly right of center in the heel and follows a path towards the left of the heel before continuing back to the right to hug the right side midfoot section of the foot. This pressure path then extends back to the left as the path moves from the midfoot into the ball of the foot and into the toe. A mirror image of this path would be provided for a left foot.

FIG. 1-3 illustrate an example sole 10, also referred to as a shoe component, having a toe section 12, a heel section 11, and a midfoot section 13 positioned therebetween. An exterior side 13A and an opposed interior side 13B (corresponding to the arch of the midfoot), both extend from the heel section 11 through the midfoot section 13 and to the toe section 12.

In an example, a closed cell foam heel cup 14 is positioned in the heel section 11. A heel pad 16 can be provided that includes any of foam, air, and a combination thereof. In one example, heel pad 16 includes an air pocket. In another example, heel pad 16 includes an open cell foam material that allows air to push through to the midfoot during use. The heel pad 16 is positioned in the heel section 11 to be at least partially surrounded by the heel cup 14.

Moving from the heel section 11 to the midfoot section 13, a plurality of open cell foam members 17 and 18 are provided. Foam members 17 and 18 can be interchangeably referred to as foam cells and can have varying firmness and/or densities. The cells 17 and 18 are positioned in a movement pattern corresponding to a user's pressure movement pattern 21 and extending through the midfoot section 13 and into the toe section 12. Cells 17 and 18 are configured to provide dynamic support and comfort to a user for walking or any designated athletic activity. The varying firmness and densities allow for customized comfort and support for any particular pressure profile.

An optional toe closed cell foam member 15 can be provided. Typically, the toe member 15 is positioned in an outer corner of the toe where minimal movement pressure exists during use of the shoe. Accordingly, placing a foam member in this particular space can help as a filler and potentially reduce costs of manufacturing.

In an example, the movement pattern 21 corresponds to a determined pressure pattern associated with a given athletic activity and the movement pattern defines a center path 20. The plurality of open cell foam members 17 and 18 are positioned on either side of the center path 20 corresponding to a movement configuration of a user to provide varying support on either side of the center path 20. In an example, the movement configuration of the user can be any of a pronator (FIG. 1), neutral (FIG. 2), and supinators (underpronators) (FIG. 3).

In a further example, members 17, 18 are fabricated from an open cell foam material to allow for air to pass through the sole 10. Members 17 and 18 can include geometries of cylindrical cells having any of soft, medium, and firm densities, and any combination thereof (e.g., soft/medium, soft/firm, medium/firm, or soft/medium/firm). Soft, medium, and firm densities can be relative terms corresponding to the relative manner in which the foam members respond to an applied load. For example, under a given compressive load (e.g., in an axial direction defined by the foam member, such as generally perpendicular to the shoe component surface), a corresponding compressive deformation (e.g., also in the axial direction defined by the foam member) is largest for the soft density, smallest for the firm density, and at an intermediate value for the medium density. In a refinement, the foam members can have a distinct color or other visible index or indicator corresponding to the foam member density and/or firmness. Such a visible index or indicator can permit a user (or other person) to reposition and/or replace foam members within a shoe component, for example to change the shoe component from one movement pattern, pressure pattern, and/or movement configuration to another (e.g., to/from pronator, neutral, and/or supinator (underpronator)).

In examples of FIG. 1-3, members 17 define firm densities and members 18 define soft densities. The firmness of the sole 10 is varied by varying members 17 and 18 about the center path 20 by rearrangement of the varying soft, medium, and firm density cells. This corresponds to support a foot of the user depending on their pressure movement profile. In yet another example, the firmness of the shoe component can be varied by increasing or decreasing the amount of cylindrical cells 17 and 18 according to a desired configuration. Example configurations can include those shown in FIGS. 1-3 or customized according to a given center path for a given pressure map. A pronator (FIG. 1) configuration can be provided having more firm cells 17 positioned interior to the center path 20 relative to a neutral configuration (FIG. 2) and more soft cells 18 positioned exterior of the center path 20 relative to a neutral configuration. A supinator configuration (FIG. 3) is provided having more firm cells 17 positioned exterior to the center path 20 relative to a neutral configuration (FIG. 2) and more soft cells 18 positioned interior of the center path relative to a neutral configuration.

The dynamic sole configurations of the present disclosure can be configured according to various athletic activities. Examples of athletic activities that may result in varying pressure movement profiles include but not limited to any one of running, hiking, golf, basketball, tennis, football, baseball, soccer, etc.

In an example, the open cell foam members 17, 18 define varying colors corresponding to varying densities and firmness. The arrangement of foam members 17, 18 about the center path 20 forms passageways 19 that allow air passage through the sole 10 corresponding to a walking pressure pattern 21 of the user from heel 11 to toe 12. In an example, the foam members are fabricated from natural rubber latex.

The present disclosure further provides for a method of customization of a user's preferred shoe sole. In this example, a user's pressure pattern can be determined. This can be performed using a scanning technique or electronically through a pressure map reader or the like. Based on a pressure mapping, a customized configuration can be made based on identifying a center line and configuring the cells of varying firmness about the center line. This will provide the desired comfort and support for that particular user.
